The Importance of UPS Batteries | Five Things To Know
23 May 2022

At P&I we understand there is a lot of information out there about generators and UPS. It can be difficult to navigate what you as a user need to look out for and understand and what your service provider will do. Our service and maintenance packages cover various aspects of UPS maintenance, but to help our clients, we’ve put together some things you should know about UPS batteries. 

A UPS battery is a key component in any uninterruptible power supply system. UPS batteries provide the backup power in the event of a power outage or other power disruption, ensuring that the critical equipment and systems can stay online and operational.

Without a properly functioning UPS battery, businesses and organisations would be at risk of data loss, downtime, loss of business and potentially loss of life in some cases. That’s why it’s important to understand the key things to know about UPS batteries: How does a UPS battery work? What type of battery does a UPS use to run? How often do I need to change my UPS Battery?

If you’re looking for more information on UPS batteries, keep reading.

1. How does a UPS battery work?

A UPS battery is a key component of an uninterruptible power supply system. UPS batteries provide the backup power to the UPS in the event of a power outage or other power disruption, ensuring that critical equipment and systems can stay online and operational.

2. What type of battery does a UPS use to run?

UPS systems typically use valve regulated lead-acid batteries (VRLA) these are named the same and are even similar looking to the type of battery used for automobiles but are actually built specifically for operating with industrial loads such as for a UPS. 

3. How often do I need to change my UPS Battery?

The lifespan of a UPS battery varies depending on the make and model of the battery, but most batteries generally need to be replaced every 3-5 years for standard life or 7-10 years for long life. The design life is how long a battery might last in optimum conditions and the service life of a battery is more indicative of real use of a battery, though this still requires temperature controlled to 20 degrees Celsius and the not allowing the battery to deep discharge. A UPS battery operating in an ambient temperature of 30 degrees Celsius would half the life span of the battery! Keeping batteries cooler is often more economical than replacing them prematurely.

4. How often do I need to have my UPS battery serviced?

UPS batteries should be serviced depending on the requirement which can be quarterly, biannually or annually in order to ensure that they are functioning properly and remain safe for use. Our team can provide you with a detailed service and maintenance package and explain how we work to ensure your UPS and battery are serviced and running efficiently.

5. What should be looked out for when inspecting a UPS battery?

The age and usage of the battery should be considered along with signs of wear and tear, such as cracks, leaks, or bulges and the connections and wiring can be inspected for any potential issues. However with VRLA maintenance free batteries it is often not possible to determine from a visual inspection alone what the actual state of the battery is. Carrying out impedance testing on the battery is a good indicator of the battery capacity and its ability to perform safely and your UPS PPM should include a full battery report on the current health of the battery blocks. A capacity discharge test is a true measure of the actual capacity and autonomy.

Maintaining a healthy UPS battery is important for any business or organisation that relies on critical equipment and systems. UPS batteries provide backup power in the event of a power outage or other power disruption, ensuring the UPS works so that businesses can stay up and running.
